This chapter describes the Darwin-Wallace theory of evolution by natural selection. In particular, it explains the notion of fitness, which underlies the concepts of descent with modification and the appearance of species categorized into clades. It shows that descent with modification is a much better evolutionary theory than the “Great chain of being” model, which implies that evolution is driven toward the production of more perfect and complex life-forms. Finally, it explains how the science of genetics strongly supports evolution through the notions of mutation, gene frequencies in populations, and drift.
